I'm going to build a new rig with a 3570K, and a EVGA 670 4GB SC(no big OCs to start with)
I'm planning go get the XSPC Raystorm 750 RS360, and XSPC Razor 670 GPU Block.
rest of the specs for the new RIG:
Sabertooth Z77
Corsair AX 860i, 860W PSU
Corsair Dominator Platinum DDR3 2400MHz 16GB (2 x 8GB)
Corsair Neutron Series GTX 240 GB
NZXT Phantom 820 Big Tower White
Corsair Air Series SP120 Quiet Edition TWIN PACK(3x for the rads

)
and of course, Corsair Professional Sleeved Cables in White!
Would you suggest I ONLY use the 360 Rad for GPU & CPU, or go for another 240 just for the GPU?
